09/08/2021, 1:27 PMThis is a circular reference issue?

JP (junaway)
09/08/2021, 1:28 PMYes. And the environment property isn't available/mutable after creating the Function, right ? If so, the circular reference would be easy to circumvent.

09/08/2021, 1:29 PMI typically store things in SSM and don't use environment variables. Then I have the lambda pull stuff during cold start

09/08/2021, 1:29 PMAnd since the server is required when creating the ApolloApi Construct, we cannot chain the operations : create API, create Function, link the two.
JP (junaway)
09/08/2021, 1:30 PMI understand but considering that it's doable with Api, since you can add the routes later, but not with ApolloApi, since the server is required at creation time, it just seems odd.

09/08/2021, 1:31 PMYeah that's fair
thdxr
09/08/2021, 1:32 PMI'm not familiar with the ApolloApi construct so not sure why it can't defer adding the function
thdxr
09/08/2021, 1:33 PMI'll take a look in a second

JP (junaway)
09/08/2021, 1:33 PMI guess, the wrapper is so light (currently) that it just didn't seem like a relevant thing to do at the time.

09/08/2021, 1:35 PMIt might be a good pattern for is to adopt to always provide functions to add things progressively and internally use them in the constructor if the props are specified
j
JP (junaway)
09/08/2021, 1:36 PMI think so. I feel like that could help solve circular references faster and easier.

09/08/2021, 1:43 PMTurns out you actually can mutate the environment afterward
thdxr
09/08/2021, 1:43 PM Copy code
const apollo = new ApolloApi(...)
apollo.serverFunction.addEnvironment(...)j

09/08/2021, 1:45 PMUgh! I checked SST methods but not CDK methods...
Thanks @thdxr

thdxr
09/08/2021, 1:45 PMAre you using typescript? I found it by looking through autocomplete options
j
JP (junaway)
09/08/2021, 1:45 PMIt had to be there somewhere...
t
thdxr
09/08/2021, 1:45 PMYeah I didn't know this existed either

JP (junaway)
09/08/2021, 1:47 PM Copy code
websocketApi.getFunction()?.addEnvironment()
apolloApi.getFunction()?.addEnvironment()JP (junaway)
09/08/2021, 1:49 PMapollo.serverFunctionGET /apolloApi.getFunction('GET /')?.addEnvironment()apolloApi.getFunction('POST /')?.addEnvironment()t
thdxr
09/08/2021, 1:52 PMIt uses the same function for both from what I can see
j
JP (junaway)
09/08/2021, 1:53 PMTrue. I could just skip the double call, assuming that that behavior never changes.
Thanks 🙂
